MIC2788

MIC2788/MIC2789 Push-Button Reset IC General Description The MIC2788/MIC2789 are low-current, ultra-small, pushbutton reset supervisors with long set-up delays. The devices feature two manual reset inputs and two reset outputs. The devices initiate a reset for the reset timeout period when the /MR0 and /MR1 inputs are asserted low for a period longer than the set-up delay. The two manual reset inputs and long set-up period help to avoid unintended system resets. Both manual reset inputs can be tied together if a single push-button reset is desired. The MIC2788 features integrated pull-up resistors on the /MR0 and /MR1 inputs, while the MIC2789 requires external pull-up resistors. The PDY input pin selects between a 2s, 4s or 6s set-up period. Factory-programmed reset timeout periods of 140ms (min.) and 240ms (min.) are available. An active-low, open-drain reset output (/RST) and an active-high, push-pull reset output (RSTP) provide flexibility when interfacing to various microcontroll...
